Wave and Tidal – Drawdown Strategy #29

71% of the Earth’s surface is water, and almost 97% of that water is in our oceans.[i] Pushed and pulled by winds, the moon’s gravitational pull, and the Earth’s rotation, all 320 million cubic miles[ii] of ocean water is constantly on the move, generating a huge amount of mechanical energy.   For the most part,…

Small Methane Digesters – Drawdown Strategy #64

Number 30 in this series is large methane digesters[i], a comparatively low-tech climate solution designed to capture the methane produced when human and animal waste and other organic matter decompose. Doing so prevents this greenhouse gas, which is as much as 86 times more potent[ii] than CO2, from entering the atmosphere. Moreover, the biogas[iii] (usually…

Large Methane Digesters – Drawdown Strategy #30

Carbon dioxide (CO2) tends to grab the headlines when it comes to greenhouse gases, but more and more attention is being paid to the effects of methane (CH4). While it’s true that carbon dioxide lasts far longer in the atmosphere—centuries to methane’s average of 9 years[i]—methane actually warms the planet 86 times as much[ii]. Moreover,…
